For use in manufacturing concreted building products in polyurethane molds, a demolding apparatus provides a clamping bar which clamps on to a lip of a mold (22) and is then moved with pivotal arms (32,34) forward and upwardly to effectively strip the edge of the mold (22) form the front end of the respective product (24). The reciprocating mold (22) passes below a roller (66) which moves into engagement with the upper surface of the mold (22) to apply a downwardly directed pressure onto the mold and product, thereby to retain the product (24) on a conveyor (12) and rollers (68), and facilitate stripping of the mold (22) from the product (24). The stripped product (24) moves onto an offtake conveyor (70) and, in the uppermost position of the arm (32,34), the clamping jaws are released to allow the stripped mold (22) to thereafter fall onto the conveyor (70).
Demoulding apparatus comprising means (12) for supporting a mould (22) which has an open side and a moulded component (24) therein, characterized in that, for use in demoulding when the mould is supported with the open side facing the supporting means (12), there is provided movable gripping means (48) for releasably gripping the mould (22), and means (32, 34) for moving the gripping means (48) in such a direction away from the support means (12) that a mould (22) formed of a flexible material, when gripped by the gripping means (48), can be stripped from one edge of the component (24) to an opposed edge thereof, whereby to remove the mould (22) from the component (24).
A demoulding method comprising the steps of supporting a flexible mould (22) with a moulded component (24) therein, and moving the mould (22) with component (24) in a linear path to a location whereat the mould (22) is clamped at one edge thereof, and then moving the mould (22) in a direction away from the supporting means (12), the component (24) continuing to move in the linear path, whereby to strip the mould (22) from one edge of the component (24) to an opposed edge thereof, whereby to remove the mould (22) from the component (24).
